Answer: 16
Step-by-step explanation:
72 is the record - 56 which the player has already scored = 16 points is what would be needed to tie the record
We have that
t²<span> – 81
</span>
we know that
A difference of two perfect squares, <span> (A</span>²<span> - B</span>²)<span> </span><span>can be factored into </span><span> (A+B) • (A-B)
</span> let
A²-------> t²
B²-------> 9²
then
(t² – 9²)------->(t+9)*(t-9)
the answer is
(t+9)*(t-9)
STEP BY STEP EXPLANATION:
4=86⁰ because the lines are parallel.
49⁰+86⁰=180
135=180
180-135
45
5=45⁰
2=49⁰ BECAUSE THE LINES ARE PARALLEL
NOW FOR ANGLE 1
45+86
131
as A & B ARE PARALLEL SO
1=131⁰
HOPE IT HELPS ;)
Answer:
Base at the top should be the same length, thus 20ft.
right triangle thus 90 degrees angle.
180 - 90 - 40 = 50
20ft/sin50 = Height/sin40
Height of the traffic light = 16.78
16.78 + the height of Andrew eyes ( 5ft) = 21.78
It’s the 2nd one have a nice day
